Association between low-frequency ultrasound and hip fractures - comparison with DXA-based BMD
2013
Background New methods for diagnosing osteoporosis and evaluating fracture risk are being developed. We aim to study the association between low-frequency (LF) axial transmission ultrasound and hip fracture risk in a population-based sample of older women. Methods The study population consisted of 490 community-dwelling women (78–82 years). Ultrasound velocity (VLF) at mid-tibia was measured in 2006 using a low-frequency scanning axial transmission device. Bone mineral density (BMD) at proximal femur measured using dual-energy x-ray absorptiometry (DXA) was used as the reference method. The fracture history of the participants was collected from December 1997 until the end of 2010. Lifestyl…
Efficacy of proteolytic enzyme bromelain on health outcomes after third molar surgery. Systematic review and meta-analysis of randomized clinical tri…
2019
Background Bromelain is a cysteine protease isolated from pineapple with a range of biological properties including platelet aggregation inhibition and anti-inflammatory effects. Recent studies have evaluated the clinical implications of bromelain in reducing postoperative inflammatory complications after third molar surgery, but the results are contrasting. This systematic review and meta-analysis evaluated the effects of bromelain on health outcomes in patients submitted to third molar surgery. Material and Methods The study was conducted following the PRISMA statement. Searches were conducted in six electronic databases and Google Scholar from inception to May 2018. The following element…
Arterial stiffness in obese CPAP-treated obstructive sleep apnea (OSA): A seven years prospective longitudinal study
2017
Introduction: Arterial stiffness measured by carotid-femoral pulse wave velocity (PWV) is elevated in severe OSA. A 1m/s increase in PWV is associated with a 15% increased risk of mortality. There is a paucity of data regarding long term evolution of PWV in CPAP-treated OSA. Aims: To measure PWV evolution in CPAP-treated OSA. Methods: In a prospective obese OSA cohort, we collected PWV, clinical and biological metabolic data, incident cardiovascular events and CPAP adherence at time of diagnosis and after at least 5-year follow-up. Results: 72 OSA (men: 52.8%, median age: 55.8 years and median BMI of 38.5 kg/m2) with a high prevalence of hypertension: 58.3%, Type 2 diabetes: 20.8%, hypercho…
Management of patients with Intestinal Bowel Disease and COVID-19: A review of current evidence and future perspectives
2022
La pandemia por COVID-19 ha supuesto un reto para los países y sus profesionales sanitarios. La entrada viral en el hospedador a través del receptor ACE-2 y una activación excesiva del sistema inmunológico son claves para comprender tanto la incidencia como la gravedad de la enfermedad. La enfermedad inflamatoria intestinal (EII) representa una condición especial asociada con una respuesta descontrolada del sistema inmunológico a agentes externos. Los tratamientos para la EII se han asociado con un mayor riesgo de infecciones bacterianas y virales. Esto ha planteado la cuestión de una posible mayor incidencia y gravedad de la infección por COVID-19 en pacientes con EII. A lo largo de este a…
Italian association for the study of the liver position statement on SARS-CoV2 vaccination.
2021
The vaccination campaign against Sars-CoV-2 commenced in Italy at the end of December 2020. The first ones to receive the immunization against the virus were the health workers and the residents of nursing homes, following which the vaccine would be available for the entire population, beginning with the most vulnerable individuals. SARS-CoV2 vaccines have been demonstrated to be safe for the general population, although no data for patients with liver diseases or those having undergone liver transplantation are available so far. The present position statement AISF is an attempt to suggest, based on the published data on the impact of Sars-Cov-2 infection in patients with chronic liver dise…
SARS-CoV-2 vs. Hepatitis Virus Infection Risk in the Hemodialysis Population: What Should We Expect?
2021
Since the dramatic rise of the coronavirus infection disease 2019 (COVID-19) pandemic, patients receiving dialysis have emerged as especially susceptible to this infection because of their impaired immunologic state, chronic inflammation and the high incidence of comorbidities. Although several strategies have thus been implemented to minimize the risk of transmission and acquisition in this population worldwide, the reported severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence varies across studies but is higher than in the general population. On the contrary, the screening for hepatitis viruses (HBV and HCV) has seen significant improvements in recent years, with va…
Therapeutic Effectiveness of Nutrition Therapy in Pediatric Patients with Chronic Liver Diseases Awaiting Liver Transplantation
2013
It is important to prevent protein/calorie malnutrition in children with end stage liver diseases prior to transplantation. This study involved 34 patients between the ages of 10 and 156 months (mean value 25.69 months ± 32.2) (13 females and 21 males) on the liver transplant waiting list. Data collected as of three months before transplant and up to ten months after the procedure concerned gender, age, weight, height, Pediatric End Stage Liver Disease Score, baseline pathology, type of nutrition, type of transplant, immunosuppression, pulse steroid therapy, length of stay, and post transplant complications. Linear regression analysis showed that the length of hospital stay was 24.5 days mo…
Screening and surveillance for hepatocellular carcinoma: perspective of a new era?
2016
Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer-related death with an increasing prevalence worldwide. Early diagnosis of HCC is important since observational studies have reported that, in patients undergoing surveillance, cancer is diagnosed at an earlier stage with increased chances of curative therapies. Anyway, despite the extensive use of screening for HCC, its effectiveness is still a controversial topic since supporting evidence is not unequivocal and some issues need to be explored. Areas covered: The aim of this paper is to review main literature data supporting performance and effectiveness of screening for early detection …
Targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement: diagnostic value for differentiating HCC from other primary live…
2021
To evaluate targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement as potential new LI-RADS features for differentiating hepatocellular carcinoma (HCC) from other non-HCC primary liver carcinomas (PLCs). This IRB-approved, retrospective study was performed at two liver transplant centers. The final population included 375 patients with pathologically proven lesions imaged between 2007 and 2017 with contrast-enhanced CT or MRI. The cohort consisted of 165 intrahepatic cholangiocarcinomas and 74 combined hepatocellular-cholangiocarcinomas, with the addition of 136 HCCs for control. Two abdominal radiologists (R1; R2) independently reviewed the imaging studies (112…
Special Considerations for Antihypertensive Agents in Dialysis Patients
2010
Hypertension is present in most patients with end-stage renal disease and likely contributes to the premature cardiovascular disease in dialysis patients. Previous practice guidelines have recommended that, in patients on chronic dialysis, blood pressure (BP) should be reduced below 130/80 mm Hg. This is based on opinions but not strong evidence, since no concrete information exists about which BP values should be the parameter to follow and which should be the target BP values. The majority of the antihypertensive agents can be used in this population, but the pharmacokinetics altered by the impaired kidney function and dialyzability influence the appropriate dosage as well as the time and…
